Wikidata is a free linked database for the structured data of its Wikimedia sister projects including Wikipedia, Wikivoyage, Wikisource and others.
The content is available under a free license, exported using standard formats, and can be interlinked to other open data sets on the linked data web.

This page provides RDF exports that are generated regularly from the content of Wikidata. The Wikidata RDF exports consist of several files that contain different parts and views of the data, and which can be used independently.
